Definitions

  • the invention relates to a method, a computer program product and a computer system for the maintenance of a technical system consisting of several system components.
  • Such technical systems generally consist of several system components that implement the individual functions of the technical system. Many of these system components are subject to mechanical wear during their service life. During the service life of the technical system, the wear of its system components poses a major problem, because if a wear limit is exceeded, the function of the technical system or at least one of its sub-functions is no longer guaranteed.
  • a disadvantage of this procedure is that components are often serviced or replaced which, because of their actual condition, would be perfectly suitable for continuing to ensure their function at least within a certain period of time. Such maintenance, which is often unnecessary, therefore leads to high financial burdens in order to ensure the safe functioning of the system components.
  • sensors are installed on the system components or in their environment and connected to monitoring devices. These generate monitoring messages, which are then generally to be interpreted by the maintenance personnel of a technical system. From this interpretation, a corresponding conclusion can be drawn regarding maintenance measures that are presumably necessary. This procedure can lead to maintenance measures being initiated too late, since monitoring is often carried out only on the basis of secondary measured values and the primary cause of the damage is therefore recorded too late or not at all.
  • a typical example of this is cavitation damage in a pump, which is primarily not measurable and can only be detected on the basis of the secondary measured values, such as the medium pressure, the medium temperature or the medium flow.
  • monitoring devices that are based on classic, analog measurement methods of pressure, temperature, speed, flow rate, etc. do not use the entire range of information, such as that contained in the noise of the signals and energy flows. In doing so, you forego a wide range of information for monitoring and diagnosing the behavior of components.
  • the initiation of maintenance measures based on sensor data can also lead to maintenance procedures being initiated unnecessarily, since the monitoring does not reflect the real wear or damage pattern based on the previously mentioned secondary measurement values, but only their symptoms, which do not necessarily have to correspond to one another.
  • the invention is therefore based on the object of specifying a method, a computer program product and a computer system for the maintenance of a technical system consisting of several system components, which ensure timely and cost-effective maintenance of the technical system.
  • the object is achieved by a method for the maintenance of a technical system consisting of several system components with the following steps:
  • the wear behavior of at least one system component is simulated. 2. At least one wear parameter is assigned to the wear behavior.
  • the future development of the value of the at least one wear parameter is forecast.
  • At least one maintenance time and / or at least one maintenance action of the relevant system component is derived from the forecast future development of the value of the at least one wear parameter.
  • the advantage of the method according to the invention is, in particular, that the time of maintenance and / or the maintenance action are based on the wear actually present. By predicting the wear behavior, it is possible to carry out the maintenance time and / or the maintenance action in a targeted manner when the wear of one or more system components has exceeded a permissible tolerance threshold. This prevents maintenance being initiated too early or too late, that is, unnecessary costs for unnecessary maintenance measures are incurred and that the maintenance action is carried out to an excessive extent that is not necessary.
  • current process data and / or archived long-term storage process data stored in at least one database are used to simulate the wear behavior.
